Dear all,     with Meraki MDM I have one managed app (CAS genesisWorld) and 2 managed Settings "Exchange ActiveSync Email" on our iOS devices.  The first Exchange setting delivers an email-account from the Exchange Server and the second the contacts out of the CRM-system.  Users are allowed to install other apps as well, such as Whatsapp, Telegram, and others. But: because of our data protection regulation in europe we are not allowed to use our company contacts with Whatsapp, ....     Therefor I need to containerize company contacts, mails and CAS genesisWorld.  I can do that with these restrictions:   1. Do not containerize work data and contacts from unmanaged apps  2. Do not containerize personal data and contacts from managed apps     But then I cannot open mail attachments, which I can only open with my managed app "CAS genesisWorld"!     I played around a lot - but didn't find a solution.  For me it seems, that I need to tell iOS that the app "CAS genesisWorld" and "Mail" are in the same container. But I cannot find something like this.     Can anybody help, please?  Best Regards,  Daniel
